I set up my companies on google apps for businesses, since the solution has tremendous advantages in collaborating online and in using Gmail's comprehensive suit of tools. With only $50 AUD per year per user it is relatively cheap as well. One advantage is the compatibility with iPhones and it allows me to set up IMAP Exchange accounts for my company emails on my iPhone synching not only my emails, but also my contacts, notes and calendar entries. I recently had to delete an email account on my iPhone though and had to find out the hard way that suddenly many of my contacts were gone as well. My iPhone didn't even know the mobile phone number of my wife any more...
I did a bit of investigating and found out how to recover, export and install these lost contacts again. Here is how it works.
Hope this was helpful and you read this blog article while you still had access to your old company email account. ;-)
